Also, my current plan is to use two of these UPS board, stacked together to provide UPS capability to a 12v 4a motor, will there be any issue?

Also if the system is not powered, and I turn the motor, the motor generate power. Does the board protect against any "backward" current produced by rotating the downstream motor??
